to a process for their preparation, and to their use for controlling undesirable vegetation.

The literature, such as, for example, U.S. Pat. No. 5,234,895, discloses herbicidally active N-alkyl-substituted 6-aryl-α-pyridones.

The herbicidal properties of the known compounds and their tolerance by crop plants are, however, only moderately satisfactory.

It was an object of the present invention to find novel N-substituted arylpyridones having improved properties and also a process for their preparation.

We have found that this object is achieved with the N-aminopyridone derivatives of the general formula I mentioned at the outset.

Compounds of the formula I are accessible by reducing compounds of the formula Ia with Raney Nickel in ethanol: ##STR4##

The novel compounds of the formula Ib are obtained, for example, by dehydrogenating compounds of the formula Ia using DDQ (2,3-dichloro-3,4-dicyanoquinone). In the abovementioned formulae, the substituents R¹ -R⁵ and also R⁸ and R¹¹ and R¹² have the meanings given at the outset. The reaction is carried out by adding a 10-fold excess of DDQ to a solution of the N-amino-substituted dihydropyridone Ia. Solvents which may be used are toluene, acetonitrile and/or xylenes. The reaction solution is stirred at from 50-150° C., in particular at 110° C., until the reaction has ended. The product is worked up by filtration through Alox n III.

The novel compounds of the formula Ia are obtained by reacting 6-aryl-2H-dihydro-α-pyrones of the general formula II with hydrazine/hydrazide hydrochlorides. ##STR5##

In the abovementioned formulae, the substituents R¹ -R⁵, R⁸ and R¹¹ -R¹² have the meanings given-at the outset. The reaction is effected by adding a hydrazine/hydrazide to a solution of a dihydropyrone II in the presence of an auxiliary base. To react the dihydropyrone II completely, it is expedient to add at least a two-fold excess of hydrazide/hydrazine and an excess of auxiliary base. Suitable auxiliary bases are tertiary alkylamines or pyridine. Solvents which can be used are methylene chloride, dichloroethane or diethyl ether. After the reaction solution has been stirred overnight, it is worked up by extraction by shaking with aqueous HCl and aqueous NaHCO₃ solution. The residue obtained after the solvent has been evaporated is taken up in toluene, catalytic amounts of PTSA (p-toluenesulfonic acid) are added, and the mixture is refluxed on a water separator. After the reaction is complete, the reaction solution is worked up by partitioning between ether and dilute NaHCO₃ solution.

The access to 6-aryl-3,4-2H-dihydro-α-pyrones of the structure IIa where R⁸ =methyl is known from the literature. For example, this can be achieved by cyclizing 5-aryl-5-oxopentanoic acids IIIa (R⁸ =CH₃) which, in turn, are obtained by processes known from the literature, either from substituted benzaldehydes V via the compound IVa (R⁸ =CH₃ ; cf. U.S. Pat. No. 5,234,895) (see route 1, diagram 1), or by a Michael addition reaction of substituted acetophenones VII with crotonic esters IX (see route 4, diagram 1).

6-Aryl-3,4-2H-dihydro-α-pyrones of the structure IIb where R⁸ ═CF₃ are obtained by cyclizing compounds of the structure IIIb, which, in turn, are accessible by a Michael addition reaction of malonic ester and 1-aryl-4,4,4-trifluoro-2-buten-1-one IVb. The latter compound is synthesized by subjecting trifluoromethyliminium salt VI and aryl methyl ketone VII to a condensation reaction (cf. Tetrahedron Lett., 1993, 34, 5711-5714) (see route 2, diagram 1).

6-Aryl-3,4-2H-dihydro-α-pyrones of the structure IIc with the cyclopropyl ring in the 4-position (R⁸ =cyclo-C₃ H₅) are accessible from 1-aryl-3-cyclopropyl-α-propen-1-one IVc, which, in turn, can be synthesized by a Knoevenagel reaction of cyclopropanecarbaldehyde VIII with arylmethyl ketone VII (cf. J. Am. Chem. Soc., 1951, 73, 3831-3837) (see route 3, diagram 1). ##STR6##

Other ways of obtaining access to 6-aryl-3,4-2H-dihydropyrones of the general structure II are shown in diagram 2. The reaction of ketene acetals X with aryl vinyl ketones IV results in compounds of the structure II (diagram 2, route 1). These are also accessible by reacting metallated aromatics XI with 3-substituted glutaric anhydrides XII. The 5-keto-5-arylcarboxylic acids of the structure III which are first obtained can be subjected to cyclocondensation by the above-described methods to give 6-aryl-3,4-2H-dihydropyrans II (diagram 2, route 2). ##STR7##

Other ways of gaining access to compounds of the formula Ib are possible via the corresponding 6-aryl-α-pyrones of the structure IIa.

For example, the reaction of an a-pyrone of the formula IIa with hydrazine hydrochloride, of the formula XIII, results in N-amino-substituted pyridones of the formula Ic (cf. J. Chem. Soc. Perkin Trans., 1979, Part 1, 8, 1957-1960). ##STR8##

Using protocols known from the literature, these N-amino-α-pyridones of the structure Ic can then be, for example, N-acylated (R¹¹ =H, R¹² =COR¹⁸, see route 1, diagram 3), N-alkylated (R¹¹ =C₁ -C₄ -alkyl, R¹² =H, see route 2, diagram 3) (Perkin Trans., 1982, N 2, 351-355; Synthesis, 1983, 1, 49-50) or converted to the N-alkenylidene compound (see route 3, diagram 3) (cf. J. Chem. Soc. Perkin Trans., 1979, Part 1, 8, 1957-1960).

Those 6-aryl-α-pyrones of the structure IIa which are used as starting compounds and which are not already known can be obtained readily by known synthesis methods. For example, 5-aryl-α-pyrones IIb (R⁸ =H) are accessible from dichlorobutadienearyl ketones (Bull. Soc. Chim. Fr., 1960, 23-28) which, in turn, can be obtained from phenyl methyl ketones and 3,3-dichloroacrolein (Bull. Soc. Chim. Fr., 1960, 23-28, see route 1, diagram 4).

A further possibility of synthesizing 6-aryl-α-pyrones of the structure IIb is to subject aryl vinyl ketones and chloroketene dimethyl acetal to a condensation reaction, followed by dehydrohalogenation hydrolysis (cf. J. Chem. Soc. Chem. Commun. 1972, 863-864; Can. J. Chem., 1975, 53, 195-200, see route 2, diagram 4).

6-Aryl-α-pyrones of the structure IIa are furthermore accessible by acid-induced cyclization of 5-aryl-3-hydroxypent-4-ynoic esters, which, in turn, are obtained by subjecting arylacetylene methyl ketones and α-bromocarboxylic esters to a Reformatzki reaction (cf. Arch. Pharm. 1961, 294, 234-239, see route 3, diagram 4).

A further example of synthesizing 6-aryl-α-pyrones of the structure IIc which may be mentioned is the cyclocondensation of α,β-unsaturated δ-keto esters, which, in turn, can be synthesized by reacting α-silyl-β,γ-unsaturated esters with arylcarbonyl chlorides (cf. J. Org. Chem, 1983, 48, 5288-5302, see route 4, diagram 4). ##STR9##

EXAMPLES

The preparation of some compounds which are provided by the present invention is described in the following text:

Example 1

5-Keto-3-methyl-5(3'trifluoromethylphenyl)pentanoic acid IIIa

A few drops of 3-trifluoromethylbromobenzene are added to a suspension of 0.72 g (0.03 mol) of magnesium filings and catalytic amounts of iodine in 10 ml of dry diethyl ether. After the solution has been heated using a hairdryer until the red color of the iodine has disappeared, a solution of 6.75 g (0.03 mol) of trifluoromethylbromobenzene in 50 ml of dry diethyl ether is slowly added dropwise. When all of the magnesium has reacted, the Grignard complex prepared is slowly added dropwise to a solution of 3.84 g (0.03 mol) of 3-methylglutaric anhydride in 80 ml of dry diethyl ether. The solution is refluxed for 4 hours and subsequently stirred overnight. For working-up, the reaction solution is poured into H₂ O and acidified by adding dilute HCl to destroy the Grignard complex. The pH of the aqueous phase is subsequently brought to 10 using semi-concentrated NaOH and washed three times using diethyl ether. After the aqueous phase has been acidified using concentrated HCl, the desired product is obtained by extracting the mixture three times using diethyl ether and subsequently drying the organic phases over Na₂ SO₄.

Yield: 6.1 g

Example 2

1-(Ethoxycarbonyl)amino-3,4-dihydro-4-methyl-6-(3'-trifluoromethylphenyl)-2-(1H)-pyridone (2.159):

A solution of 4 g (16 mmol) of 3,4-dihydro-4-methyl-6-(3'-trifluoromethylphenyl)-2-(1H)-pyrone in 100 ml dichloromethane is treated with 5.6 ml of triethylamine and 7.31 g (70 mmol) of ethyl hydrazinoformate, and the mixture is refluxed for 8 hours. After cooling, the reaction solution is washed alternately with distilled H₂ O, dilute HCl and distilled H₂ O, dried over Na₂ SO₄ and concentrated on a rotary evaporator. The oil which remains is taken up in 150 ml of toluene, the solution is treated with a spatula-tip full of PTSA and the mixture is refluxed on a water separator until the reaction is complete. For working-up, the reaction solution is washed first with dilute K₂ CO₃ solution and then with distilled H₂ O and subsequently dried over Na₂ SO₄. The oil obtained after the solvent has been evaporated in vacuo is purified by column chromatography on silica gel (eluent: toluene:acetone=95:5).

Example 3

1-(Ethoxycarbonyl)amino-4-methyl-6-(3'-trifluoromethylphenyl)-2-(1H)-pyridone (1.159):

A solution of 2.6 g (8 mmol) of 1-(ethoxycarbonyl)amino-3,4-dihydro-4-methyl-6-(3'-trifluoromethylphenyl)-2-(1H)-pyridone in 75 ml of toluene is treated with 2.3 g (10 mmol) of DDQ and the mixture is refluxed for 6 hours. After cooling, the reaction solution is filtered off by suction through Alox n and the filtrated is evaporated on a rotary evaporator. The oil which remains is purified by column chromatography on Alox n (eluent: ethyl acetate:methanol=95:5).

Yield: 1.4 g

The compounds I or the herbicidal compositions comprising them and their environmentally compatible salts of, for example, alkali metals, alkaline earth metals or ammonia and amines, or the herbicidal compositions comprising them in this form, can effect a very good control of broad-leaf weeds and grass weeds in crops such as wheat, rice, maize, soya bean and cotton without inflicting damage to the crop plants, an effect which above all is even present when low rates are applied.

Taking into consideration the various application methods, the compounds I, or compositions comprising them, can also be employed in a further number of crop plants for eliminating undesirable plants. Examples of suitable crops are the following:

Allium cepa, Ananas comosus, Arachis hypogaea, Asparagus officinalis, Beta vulgaris ssp. altissima, Beta vulgaris ssp. rapa, Brassica napus var. napus, Brassica napus var. napobrassica, Brassica rapa var. silvestris, Camellia sinensis, Carthamus tinctorius, Carya illinoinensis, Citrus limon, Citrus sinensis, Coffea arabica (Coffea canephora, Coffea liberica), Cucumis sativus, Cynodon dactylon, Daucus carota, Elaeis guineensis, Fragaria vesca, Glycine max, Gossypium hirsutum, (Gossypium arboreum, Gossypium herbaceum, Gossypium vitifolium), Helianthus annuus, Hevea brasiliensis, Hordeum vulgare, Humulus lupulus, Ipomoea batatas, Juglans regia, Lens culinaris, Linum usitatissimum, Lycopersicon lycopersicum, Malus spp., Manihot esculenta, Medicago sativa, Musa spp., Nicotiana tabacum (N. rustica), Olea europaea, Oryza sativa, Phaseolus lunatus, Phaseolus vulgaris, Picea abies, Pinus spp., Pisum sativum, Prunus avium, Prunus persica, Pyrus communis, Ribes sylvestre, Ricinus communis, Saccharum officinarum, Secale cereale, Solanum tuberosum, Sorghum bicolor (S. vulgare), Theobroma cacao, Trifolium pratense, Triticum aestivum, Triticum durum, Vicia faba, Vitis vinifera, Zea mays.

In addition, the compounds I can also be used in crops which have been made tolerant against the action of herbicides by means of breeding, including genetic engineering methods.

The herbicidal compositions, or the active ingredients, can be applied pre- or post-emergence. If the active ingredients are less well tolerated by certain crop plants, application techniques may be used in which the herbicidal compositions are sprayed, with the aid of the spraying equipment, in such a way that the leaves of the sensitive crop plants come into as little contact with the active ingredients as possible while the active ingredients reach the leaves of undesirable plants which grow under them, or the naked soil surface (post-directed, lay-by).

The compounds I, or the herbicidal compositions comprising them, can be applied by spraying, atomizing, dusting, spreading or pouring, for example in the form of directly sprayable aqueous solutions, powders, suspensions, also high-percentage aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusts, materials for spreading, or granules. The use forms depend on the intended purpose; in any case, they should guarantee the finest possible distribution of the active ingredients according to the invention.

Suitable inert additives are mineral oil fractions of medium to high boiling point, such as kerosene or diesel oil, furthermore coal tar oils and oils of vegetable or animal origin, aliphatic, cyclic and aromatic hydrocarbons, eg. paraffin, tetrahydronaphthalene, alkylated naphthalenes or their derivatives, alkylated benzenes or their derivatives, methanol, ethanol, propanol, butanol, cyclohexanol, cyclohexanone or strongly polar solvents, such as N-methylpyrrolidone or water.

Aqueous use forms can be prepared from emulsion concentrates, suspensions, pastes, wettable powders or water-dispersible granules by adding water. To prepare emulsions, pastes or oil dispersions, the substances, as such or dissolved in an oil or solvent, can be homogenized in water by means of a wetting agent, tackifier, dispersant or emulsifier. Alternatively, it is possible to prepare concentrates composed of active ingredient, wetting agent, tackifier, dispersant or emulsifier and, if desired, solvent or oil, and these concentrates are suitable for dilution with water.

Suitable surfactants are the alkali metal, alkaline earth metal and ammonium salts of aromatic sulfonic acids, eg. lignosulfonic acid, phenolsulfonic acid, naphthalenesulfonic acid and dibutylnaphthalenesulfonic acid, and of fatty acids, alkyl- and alkylarylsulfonates, alkyl sulfates, lauryl ether sulfates and fatty alcohol sulfates, and salts of sulfated hexa-, hepta- and octadecanols and of fatty alcohol glycol ethers, condensation products of sulfonated naphthalene and its derivatives with formaldehyde, condensation products of naphthalene, or naphthalenesulfonic acids, with phenyl and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alkylphenyl polyglycol ether, tributylphenyl polyglycol ether, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol/ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene alkyl ethers or polyoxypropylene alkyl ethers, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignosulfite waste liquors or methylcellulose.

Powders, material for spreading, and dusts can be prepared by mixing or grinding the active ingredients together with a solid carrier.

Granules, eg. coated granules, impregnated granules and homogeneous granules, can be prepared by binding the active ingredients to solid carriers. Solid carriers are mineral earths, such as silicas, silica gels, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate and magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers, such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas and products of vegetable origin, such as cereal meal, tree bark meal, wood meal, nutshell meal, cellulose powder, or other solid carriers.

In general, the formulations comprise from 0.01 to 95% by weight, preferably from 0.5 to 90% by weight, of active ingredient. The active ingredients are employed in a purity from 90% to 100%, preferably 95% to 100% (according to NMR spectrum).

The compounds I according to the invention can be formulated for example as follows:

I 20 parts by weight of compound No. 1.159 are dissolved in a mixture composed of 80 parts by weight of alkylated benzene, 10 parts by weight of the adduct of 8 to 10 mol of ethylene oxide to 1 mol of the oleic acid N-monoethanolamide, 5 parts by weight of calcium dodecylbenzenesulfonate and 5 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100,000 parts by weight of water and finely distributing it therein gives an aqueous dispersion comprising 0.02% by weight of the active ingredient.

II 20 parts by weight of compound No. 1.159 are dissolved in a mixture composed of 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight of the adduct of 7 mol of ethylene oxide to 1 mol of isooctylphenyl and 10 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100,000 parts by weight of water and finely distributing it therein gives an aqueous dispersion comprising 0.02% by weight of the active ingredient.

III 20 parts by weight of the active ingredient No. 1.159 are dissolved in a mixture, composed of 25 parts by weight of cyclohexanone, 65 parts by weight of a mineral oil fraction of boiling point 210 to 280° C. and 10 parts by weight of the adduct of 40 mol of ethylene oxide to 1 mol of castor oil. Pouring the solution into 100,000 parts by weight of water and finely distributing it therein gives an aqeous dispersion comprising 0.02% by weight of the active ingredient.

IV 20 parts by weight of the active ingredient No. 1.159 are mixed thoroughly with 3 parts by weight of sodium diisobutylnaphthalene-α-sulfonate, 17 parts by weight of sodium lignosulfonate from a sulfite waste liquor and 60 parts by weight of pulverulent silica gel and the mixture is ground in a hammer mill. Finely distributing the mixture in 20,000 parts by weight of water gives a spray mixture comprising 0.1% by weight of the active ingredient.

V 3 parts by weight of the active ingredient No. 1.159 are mixed with 97 parts by weight of finely divided kaolin. This gives a dust which comprises 3% by weight of the active ingredient.

VI 20 parts by weight of the active ingredient No. 1.159 are mixed intimately with 2 parts by weight of calcium dodecylbenzenesulfonate, 8 parts by weight of fatty alcohol polyglycol ether, 2 parts by weight of the sodium salt of a phenol/urea/formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil. This gives a stable oily dispersion.

To widen the spectrum of action and to achieve synergistic effects, the N-aminopyridone derivatives of the formula I may be mixed with a large number of representatives of other groups of herbicidal or growth-regulating active ingredients and then applied concomitantly. Suitable components for mixtures are, for example, diazines, 4H-1,3-benzoxazine derivatives, benzothiadiazinones, 2,6-dinitroanilines, N-phenylcarbamates, thiolcarbamates, halocarboxylic acids, triazines, amides, ureas, diphenyl ethers, triazinones, uracils, benzofuran derivatives, cyclohexane-1,3-dione derivatives having attached to them in the 2-position for example a carboxyl or carbimino group, or quinolinecarboxylic acid derivatives, imidazolinones, sulfonamides, sulfonylureas, aryloxy- or heteroaryloxyphenoxypropionic acids and their salts, esters and amides, and others.

It may furthermore be advantageous to apply the compounds I, alone or in combination with other herbicides, together with further crop protection agents, for example with pesticides or agents for controlling phytopathogenic fungi or bacteria. Also of interest is the miscibility with mineral salt solutions, which are employed for treating nutrient and trace element deficiencies. Non-phytotoxic oils and oil concentrates may also be added.

Depending on the intended aim, the season, the target plants and the growth stage, the application rates of active ingredient are from 0.001 to 3.0, preferably 0.01 to 1.0, kg of active ingredient (a.i.) per ha.

Use Examples

The herbicidal action of the N-aminopyridone derivatives of the formula I was demonstrated by greenhouse experiments:

The culture containers used were plastic flowerpots containing loamy sand with approximately 3.0% of humus as the substrate. The seeds of the test plants were sown separately for each species.

In the case of pre-emergence treatment, the active ingredients, which were suspended or emulsified in water, were applied directly after sowing by means of finely distributing nozzles. The containers were irrigated slightly to promote germination and growth and subsequently covered with translucent plastic hoods until the plants had rooted. This cover results in uniform germination of the test plants, unless germination was adversely affected by the active ingredients. The application rate for the pre-emergence treatment is 0.5 or 0.25 kg of a.i. per ha.

For the post-emergence treatment, the test plants were first grown to a plant height of from 3 to 15 cm, depending on the growth form, and only then treated with the active ingredients which were suspended or emulsified in water. To this end, the test plants were either sown directly or grown in the same containers, or grown separately as seedlings and transplanted to the test containers a few days prior to treatment. The application rate for the post-emergence treatment is 0.5 or 0.25 kg of a.i. per ha.

Depending on the species, the plants were kept at from 10-25° C. or 20-35° C. The test period extended from 2 to 4 weeks. During this time, the plants were tended, and their response to the individual treatments was evaluated.

A scale from 0 to 100 was used for the assessment. 100 means no plant emergence, or complete destruction of at least the aerial parts, and 0 means no damage, or normal course of growth.

The plants used in the greenhouse experiments comprise the following species:
